Robert Hague 11e7a52cb3 Cap data received during the protocol version exchange
Add upper bounds on the number of banner lines and line length before the SSH identification
string, analogous to OpenSSH. Also don't buffer all the data unnecessarily.

Rob Hague 5b8382de26 Serialise packets into a buffer (#1792)
A byte array is allocated to hold each plaintext packet. This removes that by adding
a buffer for that purpose.

Rob Hague af279d206a Fix SftpFileAttributes file type detection (#1688)
* Fix SftpFileAttributes file type detection

To get the file type, S_IFMT should be used as the mask. Instead it was using each file
type as the mask. It meant that e.g. a symbolic link would also show as a regular file
and a character device.

Also allow setting and retrieving the setuid/setgid/sticky bits

* fix build

mus65 752b1db8f0 Add .NET 9 target (#1480)
* Add .NET 9 target

* Disable SonarSource S3236

This following change in the runtime now causes this analyzer
to complain about some Debug.Assert calls which doesn't make sense.

https://github.com/dotnet/core/blob/main/release-notes/9.0/preview/preview7/libraries.md#debugassert-now-reports-assert-condition-by-default
https://rules.sonarsource.com/csharp/RSPEC-3236/

* make use of .NET 9 Lock type

see https://github.com/dotnet/runtime/issues/34812

* Define own Lock type to avoid ifdefs

* revert irrelevant style changes

* update global.json

* Keep net8.0 target in IntegrationTests

Co-authored-by: Rob Hague <rob.hague00@gmail.com>

* fix Package Downgrade Warning

for some reason this happens starting with .NET 9.0 RC2:

/home/mus/git/SSH.NET/test/Renci.SshNet.IntegrationTests/Renci.SshNet.IntegrationTests.csproj : error NU1605:
      Warning As Error: Detected package downgrade: BouncyCastle.Cryptography from 2.4.0 to 2.3.1. Reference the package directly from the project to select a different version.

       Renci.SshNet.IntegrationTests -> Testcontainers 3.10.0 -> BouncyCastle.Cryptography (>= 2.3.1)

* update global.json to RC2

* update global.json to .NET 9 GA

* small formatting improvements

* add on: workflow_dispatch

this is needed to re-run jobs manually from the web UI

* Publish NuGet package to GitHub Registry

only on develop branch.

* re-add empty appveyor.yml

so it doesn't fail CI until AppVeyor integration is disabled

mus65 3b55ba3a0a Update SonarAnalyzer.CSharp (#1494)
* Update SonarAnalyzer.CSharp

* fix S3993: Custom attributes should be marked with "System.AttributeUsageAttribute"

https://rules.sonarsource.com/csharp/RSPEC-3993/

* fix S6966: Awaitable method should be used

Introduced abstractions for CancellationTokenSource.CancelAsync()
and Stream.DisposeAsync() to avoid #ifdef.

Supressed pipeStream.WriteAsync because it deadlocks the test.
I assume because PipeStream doesn't override WriteAsync.

https://rules.sonarsource.com/csharp/RSPEC-6966/

temp

* fix S3431: "[ExpectedException]" should not be used

Removed the Connect() from Multifactor_PublicKeyWithEmptyPassPhrase
because the Exception is already thrown in the factory.

https://rules.sonarsource.com/csharp/RSPEC-3431/

* fix S2325: Methods and properties that don't access instance data should be static

This one is pretty redundant with CA1822 (which is also disabled in the
tests).

It caught a few more cases in the library itself, most of which can't
be changed because they are public API.

https://rules.sonarsource.com/csharp/RSPEC-2325/

* fix S127: "for" loop stop conditions should be invariant

not sure if this one is worth having. The only cases it found
are imho legitimate or not worth fixing, so I supressed them.

https://rules.sonarsource.com/csharp/RSPEC-127/

* fix S1964: An abstract class should have both abstract and concrete methods

Suppressed for public APIs, changed ExtendedReplyInfo to interface.

https://rules.sonarsource.com/csharp/RSPEC-1694/

* Remove redundant test

this is already covered by Test_PrivateKey_SSH2_Encrypted_ShouldThrowSshPassPhraseNullOrEmptyExceptionWhenPassphraseIsNull

* Revert "fix S2325: Methods and properties that don't access instance data should be static"

suppress it instead

This reverts commit 2020604958.

* Revert "fix S127: "for" loop stop conditions should be invariant"

suppress it instead

This reverts commit 1d8b4ac335.

Rob Hague 1af01692fe Port shared tests folder (#1467)
These tests were presumably once shared with the old integration tests repo
but have since been sat doing nothing. This brings them into the unit tests
project.

mus65 c0a353a4de Cleanup formatting and style and enforce it in CI (#1380)
* Preparation to enforce formatting and style in CI

- enabled IDE0055 to enforce formatting on build
- disabled SA1137 and SA1025 because they are already
  covered by IDE0055
- disabled SA1021 because it conflicts with csharp_space_after_cast

* Cleanup formatting and style on codebase

This commit has no manual changes, it is the result
of running "dotnet format whitespace" and "dotnet format style"

* new formatting fixes after merge

* appveyor: set git autocrlf

as suggested by sharwell to hopefully fix Windows CI.

* use autocrlf input

to hopefully fix Linux tests

* fix formatting

* use autocrlf input for Linux only

* set csharp_space_after_cast to false

* Revert SA1021 suppression

Rob Hague 0cfeb6bb94 Tweak AsyncSocketListener in tests (#1382)
* Tweak AsyncSocketListener in tests

Some CI runs have been crashing lately from within AsyncSocketListener.
This moves a bit of disconnection & exception handling around. It probably won't
fix the underlying tests which would have otherwise failed, but it might stop the
process from outright crashing.

Also reference the same code for the integration tests.

* Simplify the diff

* Stabilise a couple of tests
